Post up your ported cylinder Artwork

I must say off all the stuff I see and here out there...XS "Fingers" has the most improvements over the shortest time span.
Well Done

When did you pick up a spinny thingy?

5 or 6 years ago

I will add Turbulaters can be found in nature from fast diving birds and insects to humpback whales we human's are only copping what nature already knows lol

The lumps and bumps (turbulaters) on humpback whales ain't there just for good looks there for efficient drag reduction.

Remember how they said wasn't even that many years ago turbulaters will never be used in car racing or f1 there is no need!
Funny how they are slowly creeping in lol

I'm seeing a lot of low pressure and trailing edge use pictures. As for the leading edge of whale fins, I think that's more of an anti stall or anti cavitation thing when flapping in the water like leading edge vortex generators on an airplane. I don't know how much they help with drag, but certainly help prevent stalls at high angle of attack flying. Maybe turbulators don't see as much gain in high pressure systems compared to low? Maybe just because high pressure has lots of power behind it while low pressure needs all the help it can get.

Interesting stuff.

His work looks excellent. I try just not there yet

I was only going over the basics of it all didnt want to get into vortex generators as well, there is so much to it all liquid dynamics interest me I forget more than I remember. The whales flipper has less drag at the leading eage thanks to the lumps you only get a high pressure zone right in front of the lumps not the hole leading eage like a conventional plane wing is my under standing.
I read something about lexus has done testing with dimpling the hole under body of a car apparently apart from less drag they also got less noise comming into the car thanks to the nice controlled air flow under the car.
But yeah lots of reading and testing going on out there if someone is interested in this type thing.

Nice work

 

[Lightning Performance]

Outstanding. Does it work on low pressure ports? Not likely. The Stihl boot has peeks not dents just to mix air and fuel. I saw a piston once all dimpled. For holding oil and losing weight I'm told but not sold.

I would have been more surprised if adding a few hundred pounds of clay didn't use more fuel lol

If you don't polish your intake ports smooth and leave them rough or rough them up more just means you are already using the "golf ball effect" in the big picture of thing's.

Looks very nice good job.

Thanks

You're welcome that's some pretty clean porting you did.

I fixed this seized ms170 a few months ago.
While I had it apart thought I'd try something different for fun and sinence and stuffs.
For the guy's that freak out seeing something different and not the norm it's ok just breath look away and stop slow blinking you will be fine lol just Jk...
Anyways I thought it would be cool to test in my none scientific way the theory that a mirror polished exhaust port is the best as far as carban sticking to it and the like.
Well I pulled the muffler for a stickybeck today after running bout 15 to 20 (or more I wasn't counting) tanks of run time over the last few months.

I was hoping to get some indication of how things are going in there with carbon sticking and staining in the port but thanks to running wet sloppy synthetic bike oil that doesn't burn to well in saw's the last say 10 tanks of fuel it's only light staining so far but I can see a few thing's going on already.
I need to get some of me good dino oil that burns nice and clean in saw's and run it a few more months for better results.
Is just abit of fun will post more pics of how it's looking in few months.

I never polish anything but my knob
